Interesting. The 2011 doesn't need to precede the 2012 maps though, right? I'm coming from '09 maps, so my plan was to install the 2012 maps with a purchased FSC code. I assume I wouldn't need to update to 2011ii and then 2012.

No, I just did it to see what would happen. I do not even know what is the purpose of the 2011ii version as is not documented anywhere. It is just added to the order of the 2012 version for the same price.
